The only reference to an FL and CDN variation was on Beckett; without explanation. The Standard Catalog of Baseball Cards (2011) does not list any Clemens variations. The confusion could stem from the 1991 Pepsi issues. In 1991 they had a Florida-only issue of Superstars (which included Clemens) and then some regional team issues (including Boston Red Sox).
I'd say remove the variations. If sometime in the future someone finds proof of any such variations, the variations can be added. I believe only Admin can remove cards from a checklist.
Someday my cards may double in value and then be worth half of what I paid for them.
